Datrys x5/12-2/x-11

$$\frac { x 5 } { 12 } - \frac { 2 } { x - 11 }$$

Enrhifo

$$\frac{xx_{5}-11x_{5}-24}{12\left(x-11\right)}$$

Camau Ateb Byr

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin 12 a x-11 yw 12\left(x-11\right). Lluoswch \frac{x_{5}}{12} â \frac{x-11}{x-11}. Lluoswch \frac{2}{x-11} â \frac{12}{12}.

$$\frac{x_{5}\left(x-11\right)}{12\left(x-11\right)}-\frac{2\times 12}{12\left(x-11\right)}$$

Gan fod gan \frac{x_{5}\left(x-11\right)}{12\left(x-11\right)} a \frac{2\times 12}{12\left(x-11\right)} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$\frac{x_{5}\left(x-11\right)-2\times 12}{12\left(x-11\right)}$$

Gwnewch y gwaith lluosi yn x_{5}\left(x-11\right)-2\times 12.

$$\frac{x_{5}x-11x_{5}-24}{12\left(x-11\right)}$$

Ehangu 12\left(x-11\right).

$$\frac{x_{5}x-11x_{5}-24}{12x-132}$$

Ffactor

$$\frac{xx_{5}-11x_{5}-24}{12\left(x-11\right)}$$
